IMPROVEMENT IN STOP-HINGES FOR CARRIAGE-DOORS, &c.

Specification forming part of Letters Patent No. 189,920, dated April24, 1877; application tiled March 19, 1877.

To all whom 'it may concern,-

Be it known that I, GEnELEs W. BUTLER, of the city, county, and State ofNew York, have invented a new and Improved Stop- Hinge, of which thefollowing is a specifica tion:

Figure 1 is a side view of my improved hinge, closed. Fig. 2 is across-section of the same taken through line a: fr, Fig. l, and Fig. 3is a top view of the same opened.

The object of this invention is to furnish improved hinges forcarriagedoors, trunks, and other similar uses, to stop the doors,covers, and other objects to which they are attached when they have beenopened to about right angles.

The invention consists in the two bars hinged to each other at theirinner ends, and at their outer ends hinged to the outer edges of theslotted plates or wings of a hinge, as hereinafter fully described.

A and B are the main plates or Wings of the hinge, which are hinged toeach other at one edge in the usual way. The wings or plates A B areslotted from their f'ree edges nearly to their hinged edges, and in theslots thus formed are placed bars C D, which are hinged to each other attheir inner ends, as shown in Figs. l, 2, and 3. The outer ends of thebars C D are hinged to thepouter or free edges of the plates or wings AB, as shown in Figs. l, 2, and 3. By this construction the hinged bars GD act as a stop or tie brace, to prevent the plates or wings A B fromopening beyond a certain point fixed by the length of the bars C D.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The bars C D, hinged to each other at their innerends, and at their outer ends hinged to the outer edges of the siottedplates or wings A B of a hinge, substantially as herein shown anddescribed.

CHARLES W. BUTLER.
